1Cleaner: Phone & File Cleaner

1Cleaner is a private phone and file cleaner. Find similar photos, duplicates, big files and junk, review the results and remove only what you confirm. Every scan runs on your device.

No ads. No tracking. No account.

Smart Clean
One scan finds similar photos and bursts (the best shot is kept), exact duplicate photos and videos, possible duplicate videos, screenshots, large and old videos, large photos, duplicate contacts and old calendar events. Access to all files adds big files, duplicate files and junk.
Complete, successful file scans with the same storage and protection settings show which top-level folders grew or shrank since the previous scan. The first sets a baseline. Open a folder to review its current files; nothing is preselected.

Files Cleanup
Clean up shared storage from one screen:
• Big files from 10 MB, by size and type: videos, archives, installers, documents
• Duplicate files, verified byte by byte; one copy always kept
• Junk: temporary files, unfinished downloads, old logs, thumbnail caches, leftovers such as LOST.DIR and computer trash folders, empty folders, old APK installers
• Messenger media saved to shared storage by WhatsApp, Telegram and Viber, by app, type and age: photos, videos, audio and documents. Chats, databases and backups are never touched.

Why 1Cleaner asks for access to all files
Finding and removing big, duplicate and junk files across shared storage is its core job. Android's media library and individually selected folders cannot reach all the installers, logs, leftovers and empty folders. Android asks once for all-files access, used only to scan and clean on your device. Android/data and Android/obb are never read; nothing is uploaded. If you decline, photos and videos are still checked.

External app caches
From Home, ask Android to clear external app caches through its own confirmation (Android 11+). Internal app caches and personal data stay unchanged. Apps can recreate caches. No per-app breakdown or promised saving.

Protected files and folders
Choose shared-storage paths in Settings to exclude them and their contents from 1Cleaner's cleanup suggestions and deletion, including older results and App Bin. Protection does not follow moves or renames or control Android's cache clearing.

Storage details
See what fills storage, the largest folders and Android's trash, which you can empty after confirmation.

Compress videos and photos
Create smaller copies on your device, with an estimated saving per quality. Every copy is checked before saving; originals stay unchanged.

Swipe Clean
Review photos and videos month by month: swipe left for App Bin, right to keep, with Undo.

Contacts and calendar
Merge duplicate contacts, choosing the card to keep; a protected local backup can restore removed cards. Remove events that ended over a year ago, never a whole repeating series. Contact access is requested for merging.

Private Vault
Encrypted copies of photos and files behind a PIN or biometrics, only on this device.

Nothing deleted by surprise
Photos and videos wait in App Bin until confirmed, then go to Android's trash, recoverable for about 30 days (Android 11+). Other files are deleted after a confirmation explaining what happens. Big files and installers are never preselected. No fake scans, alarming warnings or invented sizes.

Premium
Every tool works without a subscription. Optional Premium removes the reminder before scans and cleanups and the 10-swipes-a-day limit in Swipe Clean. Weekly, monthly and yearly plans, no trials; cancel anytime in Google Play.

In 22 languages, with launcher shortcuts. Made by an independent developer; the first app of 1Buck Apps.
